What is the preferred antibiotic for treating odontogenic infections?

The preferred antibiotic for treating odontogenic infections is Penicillin VK. This choice is based on its effectiveness against the types of bacteria commonly responsible for dental infections, particularly streptococci and some anaerobic bacteria found in the oral cavity. Penicillin VK is a narrow-spectrum antibiotic that effectively targets the specific bacterial flora associated with odontogenic infections while minimizing the risk of disrupting beneficial bacteria in the body.

Odontogenic infections typically involve polymicrobial populations, which means that an antibiotic needs to have a broad enough spectrum to cover the likely pathogens. Penicillin VK meets this requirement well, making it the first-line treatment in many cases following dental procedures, unexplained dental pain, or signs of infection.

The other antibiotic options have specific uses but do not possess the same level of effectiveness for odontogenic infections as Penicillin VK. For instance, Amoxicillin is broader than Penicillin VK and is used in various infections but may not be the first choice for odontogenic issues specifically due to its broader coverage. Cloxacillin, while helpful against certain resistant strains of bacteria, does not typically cover the common pathogens associated with dental infections. Azithromycin is a macrolide antibiotic that has its place in treatment, especially for patients allergic to penicillin;
